In Naples, throughout an allied bombing, the businessman Domenico Soriano meets the years of age whore Filumena Marturano in a brothel in the 2nd World War. Two decades later, in the post they meet each other and begin a very long affair. Filumena administrates his shops and is his mistress while Domenico is currently now traveling. Filumena ignites him if she were near to death and he marries her when Domenico makes the decision to wed the cashier of the bakery. Later he annuls their matrimony, and she informs him she has three sons she increased covertly, certainly one is his son but she doesn't disclose his identity. The different subterfuges trying to find that teen-ager might be his own son are used by the middle-age Domenico.
